Method Detail

toGrpcStatusCode

public static io.grpc.Status.Code toGrpcStatusCode(FlightStatusCode code)

Convert from a Flight status code to a gRPC status code.

fromGrpcStatusCode

public static FlightStatusCode fromGrpcStatusCode(io.grpc.Status.Code code)

Convert from a gRPC status code to a Flight status code.

fromGrpcStatusAndTrailers

public static CallStatus fromGrpcStatusAndTrailers(io.grpc.Status status,
                                                   io.grpc.Metadata trailers)

Convert from a gRPC Status & trailers to a Flight status.

fromGrpcStatus

public static CallStatus fromGrpcStatus(io.grpc.Status status)

Convert from a gRPC status to a Flight status.

toGrpcStatus

public static io.grpc.Status toGrpcStatus(CallStatus status)

Convert from a Flight status to a gRPC status.

fromGrpcRuntimeException

public static FlightRuntimeException fromGrpcRuntimeException(io.grpc.StatusRuntimeException sre)

Convert from a gRPC exception to a Flight exception.

fromThrowable

public static FlightRuntimeException fromThrowable(Throwable t)

Convert arbitrary exceptions to a FlightRuntimeException.

toGrpcException
```
public static Throwable toGrpcException(Throwable ex)
```
Convert arbitrary exceptions to a StatusRuntimeException or StatusException.
Such exceptions can be passed to StreamObserver.onError(Throwable) and will give the client a reasonable error message.

wrapIterator

public static <FROM,TO> Iterator<TO> wrapIterator(Iterator<FROM> fromIterator,
                                                  Function<? super FROM,? extends TO> transformer)

Maps a transformation function to the elements of an iterator, while wrapping exceptions in FlightRuntimeException.
